Essentially all of the "research" published on the accuracy and validity of these tests is generated by those promoting (and profiting) from them. Because these tests are only being used in the criminal justice/ family court/professional health program settings and it is not a competitive market there is no impetus for research aimed at contradicting any of it so no counter-studies exist, If these tests were being used on, for example, employees represented by a union they certainly would but no organization that has anyone looking out for the best interests of its members would ever allow this testing to begin with. The accuracy of those performing these tests needs to be questioned. So too does their integrity. https://disruptedphysician.com/2014/11/07/integrity-and-accountability-the-declining-state-of-physician-health-programs-and-the-urgent-need-for-ethical-and-evidence-based-leadership/
